It’s been a good week for graphene usage in the cement and concrete industries, with a trial set to take place at Breedon Group’s Hope cement plant and the inclusion of four graphene projects in the Global Cement & Concrete Association’s (GCCA) shortlist for its second second Innovandi Open Challenge.
The trial at the Hope cement plant was scheduled to take place on 28 June 2023, alongside First Graphene, Morgan Sindall Construction and the University of Manchester. The plan was to use 1.2t of First Graphene’s PureGraph product by testing different dispersion methods and dosage rates. The graphene was going to be prepared as a grinding aid and then added to cement grinding mill feed. Dispersion into the cement production line was planned to occur over a 24-hour period using traditional grinding aid dosage lines, with minimal operational or mechanical change required to the existing plant.
The cement produced was then going to be validated by Breedon’s quality control team to assess its performance enhancement. Overall the trial was going to produce around 2000t of graphene-enhanced cement during the trial. This cement will then be passed to Morgan Sindall Construction for real-world construction demonstrations. First Graphene reckoned that the trial was going to produce the largest volume of graphene-enhanced cement manufactured to date.
First Graphene and the other partners haven’t released any information yet on how the trial went. However, the results will be used to build on data obtained from smaller scale trials previously conducted at a concrete processing laboratory in the UK.
Elsewhere, the 15 projects shortlisted by the GCCA, as part of the Innovandi Open Challenge, were set to pitch their ideas for access to the scheme. The benefits of inclusion on the scheme include access to industry plants, laboratories, networks and the expertise and infrastructure of the manufacturer members of the association. 70 applications were made for the second Innovandi round. The first round in 2021 was focused on carbon capture and utilisation and two projects eventually made it to the pilot stage. This time the emphasis is on low-carbon concrete.
The graphene-related contenders for Innovandi in the current round include Nano Crete, Nanospan India, SeaMix and Versarien Graphene. All four companies are promoting concrete admixtures that use graphene. Given the brief for this Innovandi round, these projects are focused on concrete production as opposed to the trial at the Hope cement plant, mentioned above, which is testing graphene addition during cement grinding.
Nanospan India, for example, is promoting its Spanocrete product. It says that its admixture acts as a superplasticizer and accelerator, allowing for reduced cement and water consumption, a shorter curing cycle and an increase in compressive strength. US-based SeaMix (part of MEP Group), meanwhile, has developed its own concrete admixture that uses chopped basalt fibres and graphene. It too offers greater compressive strength and reduced cement consumption for the resulting concrete. However, it also allows for the use of any non-potable water source, a compelling selling point for construction companies trying to minimise the use of drinking water.
It is early days yet for the application of graphene in the cement and concrete sectors. Graphene was first produced at the University of Manchester in 2004. Just under 20 years later and various products are emerging with test projects slowly gathering pace and even commercial applications, such as SeaMix and others, building up their portfolios. Various challenges such as reduced workability, the high cost of graphene or even concerns about simply handling graphene get raised in discussions about the wider adoption of graphene-based admixtures but so far these do not seem insurmountable. We await the outcomes of the trial at Hope and the selections of the second round of Innovandi.
Global Cement and Concrete Association prepares shortlist for Innovandi Open Challenge 2023
19 May 2023World: The Global Cement and Concrete Association (GCCA) has received over 70 submissions to its Innovandi Open Challenge 2023, and is now preparing the shortlist of startups to present their pitches on 30 June 2023. The Innovandi Open Challenge seeks new disruptive technologies to help to achieve net zero cement and concrete production by 2050. Startups selected under the challenge will have the opportunity to partner with the GCCA and its members to further develop their products.
GCCA cement director and innovation lead Claude Loréa said “To receive more than 70 quality applications from start-ups for this year’s Innovandi Open Challenge is hugely encouraging, and shows what level of interest and work is being done to help drive climate action, with applications received from every region of the world." She concluded "Our vital industry needs products which are affordable, scalable and easily adopted. We look forward to sifting through the applications with our member companies and working with those who are selected.”
Colombia: Federación Interamericana del Cemento (FICEM) and the Global Cement and Concrete Association (GCCA) have announced their next steps to accelerate the decarbonisation of cement production in Latin America and the Caribbean. The partners have named Colombia as the region’s first Net Zero Accelerator host country. The initiative works to identify barriers to decarbonisation and to recommend policy changes to make an immediate impact. Along with fellow Net Zero Accelerator host countries Egypt, India and Thailand, Colombia brings the total coverage of the initiative to 10% of global cement capacity.
GCCA chief executive officer Thomas Guillot said “The urgency of addressing climate change becomes clearer every day. Last year, our industry made a breakthrough Net Zero global commitment to reduce our carbon footprint, and we are now driving action in Latin America to make real change in one of the regions predicted to use the most concrete and cement in the coming decades. Our Roadmap Accelerator programme, previewed today by our members and affiliate (FICEM) at Latin America and the Caribbean Climate Week, highlights the tailored policies and tools we will use to ensure that Net Zero concrete and cement is achieved by 2050.”
US: The Global Cement and Concrete Association (GCCA) hosted chief executive officers (CEO)from across the global cement industry at its CEO Gathering in Atlanta, Georgia, on 9 June 2022. The event explored the best ways for the sector to progress towards net zero CO2 emissions. Speakers included: UN special advisor on climate Selwin Hart, US Department of Energy assistant secretary for fossil energy and carbon management in the Brad Crabtree, architecture firm Gensler CEO Diane Hoskins, Chair of Oil and Gas Climate Initiative (OGCI) executive chair Bjorn Otto and climate economist Gernot Wagner.
GCCA CEO Thomas Guillot said “To achieve net zero and enable the delivery of the sustainable built environment of the future, there needs to be ongoing engagement and deeper collaboration between our industry and government in the years ahead. Targeted government policy will be vital to removing barriers and to expediting our industry’s decarbonisation plans.”
Forty cement and concrete companies commit to the Global Cement and Concrete Association’s Roadmap to Net Zero
12 October 2021World: Forty cement and concrete producers, representing 80% of concrete production outside of China in 2020, have together affirmed their commitment to the Global Cement and Concrete Association (GCCA)’s Roadmap to Net Zero concrete decarbonisation strategy. The roadmap’s seven-point plan consists of increased cement plant efficiency, which should eliminate 22% of emissions, increased concrete production efficiency (11%), adjustments to cement and binders (9%), decarbonisation of raw materials (11%), carbon capture and storage (CCS) (36%), a transition to renewable energy (5%) and the natural recarbonation of concrete (6%).
Besides full decarbonisation by 2050, the strategy provides for a 25% reduction in the global concrete sector’s CO2 emissions by 2030 and the elimination of 4.9Bnt of CO2 emissions by 2030 alone. The GCCA called the new commitment a ‘significant acceleration’ of cement and concrete producers’ on-going decarbonisation efforts, and said that it represented ‘the biggest global commitment by any industry’ to carbon neutrality. Acknowledging the burden on cement producers, the GCCA called on downstream companies and governments to support the industry’s transition.
GCCA member China National Building Material (CNBM) CEO Cao Jianglin said “This is a landmark for industry co-operation in decarbonisation. As part of a global industry, it will need collaboration across our sector to achieve it. As one of the leading cement and concrete producers in China, we will play our part in decarbonising the industry.”
Credit and quarries
07 July 2021There was good news from the corporate finance sector for cement producers this week in the form of an approving statement by Fitch Ratings. It declared that it expected the sector to be able to pass on the costs of decarbonisation to customers due to a lack of alternatives. It recognised the challenges posed by regulators, investors and societal pressure but, even so, it suggested that cement was still an industry worth backing. Or at least for now. Added to this, it forecast that demand for building materials would grow to support the transition to a low carbon economy and to combat the damage caused by climate change. It did admit that the capital or operating costs required to decarbonise are seen as being potentially large, especially with uncertainty over how much governments will pay or incentivise. Yet the timescales involved are beyond the ratings agency’s ‘horizon’ hence no really disruptive shifts in producer economics are expected anytime soon.
This was obviously a win for the cement industry and its cheerleading associations led by the Global Cement and Concrete Association (GCCA), the World Cement Association and the regional associations. After all, the increasingly convergent message to the wider world has been along the lines of ‘concrete is part of the solution and you need our products because there’s nothing else.’ Good timing then for the GCCA to launch its collaboration with the World Economic Forum, the ‘Concrete Action for Climate’ (CAC) initiative. The collaborative platform is planned to help drive the industry’s journey to carbon neutral concrete by 2050 as part of the wider Mission Possible Partnership, a wider coalition of public and private organisations working on setting the heavy industry and transport sectors towards net-zero. Expect lots more of these kinds of announcements on the road to the 26th UN Climate Change Conference of the Parties (COP26) taking place in Scotland in late October 2021.
Fitch Ratings did point out that societal awareness was likely to accelerate decarbonisation. The sharp end of this trend was experienced by the building materials industry this week when environmental activist group Extinction Rebellion forced operations to stop temporarily at LafargeHolcim’s Port de Javel ready-mixed concrete plant in Paris on 30 June 2021. This followed a similar incident by the same group at a LafargeHolcim subsidiary ready-mix plant in London in mid-2019. Given the share of global CO2 emissions from the cement-concrete production chain, it is perhaps surprising that climate activists haven’t targeted clinker-producing cement plants directly in the same way that they have gone after coal-fired power stations. Clinker kilns are, after all, the source of the majority of the sector’s emissions. However, blockading a concrete plant in the city may conjure up a more potent media image than doing the same to a factory out in the country.
Instead the battles with cement plants and their quarries tend to be of a ‘not in my back yard’ (Nimby) nature. Or rather ‘not in my monastery (Nimmon?) this week, with the news that a subsidiary of YTL Cement in Malaysia is attempting to evict a group of Buddhist monks and their underground place of worship from a quarry on Mount Kanthan in Perak. In the latest twist of the long running saga, the monks have hit back with an attempt to get their portion of the site recognised as a place of worship and a heritage site. Thankfully a more positive example of how quarries can fit in with the wider community could be found this week in the guise of an archaeological dig at CRH subsidiary Tarmac’s Knobb’s Farm quarry in Cambridgeshire, UK. The discovery of a Roman Britain-era cemetery with a high proportion of decapitated bodies may have been gruesome but the relations between the operator and the archaeologists were much more harmonious. Another recent example was the discovery of what may be a new precursor species of humans, unearthed at a quarry run by Nesher-Israel Cement Enterprises site at Ramla in late June 2021.
The paradox building materials producers pose to environmental activists could be summed up by the record heat wave that hit the north-western region of North America recently. CO2 emissions, in minor part produced by the cement and concrete industries, are the most likely reason for an increased frequency of extreme weather events such as this. Yet, infrastructure such as pavements and roads were widely reported as having buckled in the heat, principally because they weren’t built for such high temperatures. They will have to be rebuilt to withstand similar temperatures in the future. Building materials can thus be seen as both part of the problem and part of the solution. Yet with net zero targets nearly 30 years away it seems likely that continued extreme weather events and their potentially lethal consequences will speed up the public demand for decarbonisation. It is worth noting here that one of Extinction Rebellion’s demands in the UK is that the country should become net zero by 2025.
Fitch Ratings has cast its vote for now and Extinction Rebellion and its fellows are set to continue to wage their political campaigns. In the meantime it is debatable how much spiritual solace will be found by the monks of Mount Kanthan during blasting hours at the neighbouring quarry.
UK: The Global Cement and Concrete Association (GCCA) has launched Concrete Action for Climate (CAC) in partnership with the World Economic Forum. The GCCA says that CAC will support industry, civil society, governments and investors to coordinate global climate actions towards 2050 net-zero targets. The initiative represents 40% of the global concrete and cement industry through the GCCA and will bring it together with external expertise and influence. It will achieve its aims by helping to help deliver and coordinate global climate action, stimulating demand for sustainable materials and ensuring appropriate financing and public policy is in place to help the sector reduce its carbon footprint, according to the association.
CAC chair Dominik von Achten said, “Concrete is vital to the development of the modern world, being used to develop key infrastructure like safe homes, bridges and hospitals, as well as supporting the transition to clean energy. Strong action to improve the sustainability of cement and concrete is already underway, but the industry needs to engage and collaborate with others to help drive collective action towards achieving carbon neutral concrete for the world. Today’s launch of the CAC platform is a great example of such collective action. It’s encouraging and exciting to see influential, global organisations from across the world come together to support the cement and concrete industry on its path to carbon neutrality.”
Mexico: Grupo Cementos de Chihuahua (GCC) has joined other members of the UK-based Global Cement and Concrete Association(GCCA) in committing to carbon-neutral concrete production by 2050. The association launched the ambition in September 2020.
GCC chief executive officer Enrique Escalante said, “Sustainability is an important element of our long-term strategy. GCC is committed to implementing global best practices throughout the organisation while further strengthening the Company’s long-term profitability.”
Global Cement and Concrete Association announces 2050 Climate Ambition
01 September 2020UK: The Global Cement and Concrete Association (GCCA) has published its 2050 Climate Ambition, a joint industry commitment to net-zero carbon dioxide (CO2) emissions by 2050. The association’s 40 members have committed to, “eliminating direct energy-related emissions and maximizing the co-processing of waste from other industries, reducing and eliminating indirect energy emissions through renewable electricity sources, reducing process emissions through new technologies and deployment of carbon capture at scale, reducing the content of both clinker in cement and cement in concrete, as well as more efficient use of concrete in buildings and infrastructure, reprocessing concrete from construction and demolition waste to produce recycled aggregates to be used in concrete manufacturing and quantifying and enhancing the level of CO2 uptake of concrete through re-carbonation and enhanced re-carbonation in a circular economy, whole-life context.”
President Albert Manifold said, “The 2050 Climate Ambition represents our industry’s commitment to further reducing emissions and ensuring that the vital product we provide can be delivered on a carbon-neutral basis by 2050. There is a significant challenge involved in doing so and achieving alignment across our industry on a sustainable way forward is an important first step. We cannot however succeed alone and in launching our ambition statement we are also highlighting the need for our industry to work collaboratively with other stakeholders in support of our ambition for a more sustainable future.”
Sustainable thinking
01 July 2020HeidelbergCement released their sustainability report for 2019 this week. Every large cement producer publishes one but this one is worth checking out because of the company’s ambition to become CO2 neutral. Other companies are heading the same way but few of them have such developed and public plans.
Sustainability reports are often a hodgepodge of non-financial reporting bringing together environment, health and safety, community and other topics. Multinational companies cover a wide range of jurisdictions and combining reporting in these kinds of fields can be beneficial. Typically they are members of various bodies like the Global Reporting Initiative (GRI) or the Global Cement & Concrete Association (GCCA) that give various levels of conformity between reports. Yet, the wider focus of sustainability reports gives companies a chance to promote what they are doing well, away from balance sheets.
One highlight of HeidelbergCement’s report is its progress towards reducing its specific CO2 emissions per tonne of cement and its recognition by the Science Based Targets (SBT) initiative towards this goal. So far it has achieved a reduction of around 22% from 1990 levels to 599kg CO2/t (net) with a target of a 30% reduction or 520kg CO2/t by 2030. There is a lot more going on in the report but it’s led by the vision, ‘to offer CO2-neutral concrete by 2050 at the latest.’ It plans to achieve this by increasing the proportion of alternative CO2-neutral raw materials and fuels, developing lower clinker cement types and capturing and utilising CO2 emissions. A focus on concrete is worth noting given the pivot by building materials manufactures towards concrete in recent years.
Back in the present, HeidelbergCement is roughly in the middle of the pack of major European multinational cement producers with its specific CO2 emissions for cement in 2019. LafargeHolcim reported 561kg CO2/t and Cemex reported 622kg CO2/t. This is a bit of a moving target since corporate acquisitions and divestments can change both the starting point and the apparent current progress. HeidelbergCement’s acquisition of Italcementi in 2017 or CRH’s purchase of Ash Grove did exactly that. The other thing to consider is that these companies manufacture a lot of cement. The actual gross CO2 emissions from a multinational cement producer are immense. LafargeHolcim, one of the world’s largest multinational producers, emitted 113Mt of CO2 in 2019 from process and fuel sources whilst making cement. To put that into context, estimates for total global CO2 emissions range from 33 – 36Gt for 2019. The cement industry’s entire share was estimated by the International Energy Agency (IEA) to be 4.1Gt in 2018.
Where this sustainability report starts to become really interesting is where it talks about CO2 capture and utilisation. Its plans in this department are more mature than many of its competitors with various initiatives at different levels of development, mostly in Europe. Norcem, its Norwegian subsidiary, recently signed an agreement with Aker Solutions to order a CO2 capture, liquification and intermediate storage plant at its integrated Brevik cement plant. The deal is dependent on government support but it’s a serious proposal. As reported previously from the Innovation in Industrial Carbon Capture Conference 2020, HeidelbergCement is actively preparing to hook up with CO2 transport and storage infrastructure. The driver is CO2 pricing from initiatives like the European Union (EU) Emissions Trading Scheme (ETS). With the EU preparing for the next phase of the ETS and talk of the European Green Deal gathering pace, before the coronavirus outbreak at least, CO2 prices in Europe look set to rise. HeidelbergCement is positioning itself to benefit from being the first major cement producer to head into CO2 capture and storage/utilisation with a variety of methods intended for different CO2 prices and regional requirements.
HeidelbergCement doesn’t mention the coronavirus pandemic in its latest sustainability report. The report covers 2019 after all, before all of this happened. These reports do include health and safety information of employees, so this may be something to look out for next year. However, Cemex did mention the coronavirus in relation to its climate action plans this week. Essentially it wants to maintain its plans as a ‘fundamental component’ of its efforts to recover from the health crisis. This chimes with media talk around so-called ‘green-led’ government-backed relief programmes. Governments are the ones who are likely to be handing out the money, probably in the form of infrastructure projects. So it’s the perfect opportunity for them to encourage change from the companies bidding for this funding. Sustainability reports and the information behind them will be a useful tool in accessing this cash.
